Specification

500mm Single Core BC Strand LSF Insulation 6491B 450/750V Power Cable

Allowable Ampacity for 500mm Single Core BC Strand LSF Insulation 6491B 450/750V Power Cable: 100 Amps

About:

This power cable is designed with a single bare copper (BC) stranded conductor and features low smoke and fume (LSF) insulation. It operates at a voltage rating of 450/750V. Its LSF insulation ensures minimal smoke and toxic emissions in the event of a fire, making it suitable for installations where safety and minimization of fire hazards are critical.

Also Known As:

• LSF Single Core Stranded Cable
• 6491B Low Smoke Power Cable
• 450/750V Single Core LSF Cable

Application:

LSF insulated only cable for fixed wiring purposes. Used in trunking or conduit, or may be surface mounted when used for earthing. Especially for use in areas where fire would create dense smoke and toxic fumes causing a major threat to life and equipment.

Construction:

• In accordance with BS EN 50525-3-41 and Cenelec harmonised codes
H07Z-U (Solid conductors)
H07Z-R (Stranded conductors)
• Conductor: Solid Class 1 or Stranded Class 2 copper conductors to BS EN 60228
• Insulation: Low smoke zero halogen thermosetting insulation Type EI.5 to BS EN 50363-5, displaying following characteristics: Oxygen Index: 30% minimum HCL emission @ 800°C: 0.5% maximum
• Flame retardant to BS EN 60332-2-2 (up to and incl.1.0mm2) and BS EN 60332-1-2 (above 1.0mm2)
• Temperature Rating: 90°C maximum conductor operating temperature
• Voltage Rating: Up to and including 1.0mm2 300/500 V 1.5mm2 and above - 450/750 V.

Standards:

The specific standards this cable adheres to may vary depending on the region and manufacturer. Commonly associated standards might include:
• IEC 60228 (Conductor)
